Objective To investigate the protective effect of Xinyi capsule pretreatment on myocardial ischemia reperfusion injury in rabbits and its possible mechanism. Methods Ninety-four rabbits were randomly divided into 6 groups: model group (n=16), tirofiban group (n=16), high-, medium- and low-dose Xinyi capsule groups (4.0, 2.0, 1.0 g/kg;n=16 in each group), and sham operation group (n=14). Five days after intragastric administration with drug, myocardial ischemia reperfusion was induced by ligation of the proximal left circumflex artery. The electrocardiogram (ECG) was continuously recorded. The serum levels of myeloperoxidase (MPO), lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured. Myocardial histopathological damage was evaluated. Results The changes of J-point amplitude on ECG in high-, medium-and low-dose Xinyi capsule groups (0.064 ± 0.049 mV, 0.069 ± 0.061 mV, 0.079 ± 0.060 mV) were significantly lower than that in the model group (0.158 ± 0.105 mV, P<0.01 or P<0.05), the serum levels of LDH (399.7 ± 202.3 U/L, 369.6 ± 229.0 U/L, 435.5 ± 152.4 U/L), CK-MB (900.8 ± 231.2 U/L, 1 268.3 ± 899.8 U/L, 1 386.7 ± 621.6 U/L), MPO (69.81 ± 5.51 U/L, 85.44 ± 10.31 U/L, 81.33 ± 16.87 U/L) were significantly lower than those in the model group (LDH:817.1 ± 401.9 U/L, CK-MB:2 071.3 ± 693.5 U/L, MPO:149.9 ± 20.11 U/L;P<0.01 or P<0.05). Histopathological examination showed that myocardial damage in high-, medium- and low-dose Xinyi capsule groups reduced compared with the model group. Conclusions Xinyi capsule pretreatment can protect against myocardial ischemia reperfusion injury in rabbits, and its mechanism may be related to inflammation inhibition.

OBJECTIVETo study the rules of occurrence and development of TCM syndromes in patients of depression by analysing the population distribution and related factors of it.

METHODSA clinical epidemiologic survey was carried out with the materials collected by the four-diagnostic method from patients of depression to gain the syndrome types of 397 patients through dynamic cluster analysis, factor analysis and TCM syndrome differentiation. The constitution of syndrome types in different population and the relation between TCM syndrome types and the clinical types differentiated by Western medicine of depression was analyzed.

RESULTSSix syndrome types were found in 397 patients with depression. They were, ranging in occurrence order, the Gan-Qi stagnation with mental uneasiness type (108 cases, 27.2%); the Xin-Pi deficiency with dampness retention type (94 cases, 23.7%); the Xin-Gan Qi-stagnation with Phlegm retention type (76 cases, 19.1%); the Xin-Gan Qi stagnation with Jing-Luo disharmony type (57 cases, 14.3%); the Xin-Shen Qi stagnation with collateral obstruction type (34 cases, 8.6%); and the Xin-Gan Qi stagnation with Heat interfering mental type (28 cases, 7.1%). There were statistical significance (P < 0.01) in comparison of the syndrome types constitution among patients of different ages or different Western medicinal types (mild, with or without psychotic symptoms), but no significant difference was shown in that among patients of different sexes, with or without familial history of mental diseases, with monophasic or biphasic, initial or recurrent episode (P > 0.05).

CONCLUSIONThe result obtained in this study is basically in accord with the cognitive rule of TCM theory, it provides a reliable base of syndrome differentiation for treatment.

Objective To observe prospectively and systematically the effect and safety of rhendostati injection (endostar) combined with FOLFOX as a second line chemotherapy for advanced/metastatic colorectal cancer. Methods 23 patients with histological confirmed advanced/metastatic colorectal cancer after first line chemotherapy failure were observed. The dosage of 15 mg/time of endostar solved in 500ml normal saline was slowly intravenously dropped 4 h from day 1 to day 14. Oxaliplatin 85 mg/m~2 iv 2-3 h dl, d15. CF 200 mg/m~2 iv 2 h followed by 5-Fu 400 mg iv bolus and 5-Fu 600 mg/m~2 iv 22 h dl-2, d15-16 were given, every 4 weeks as one cycle. Efficacy was evaluated after 2 cycles according to RECIST criteria. Results 23 cases had been completed totally 56 cycles. Among 23 cases, 8 cases were PR, 12 cases SD, and 3 cases PD. The objective response rate (RR) was 34.8 % (8/23), and the disease control rate (DCR) was 87.0 % (20/23). The median time to progression was 7 months. The 1-year survival rate were 50.0 %. The 2-year survival rate was 40.0 %. The occurrence rate of G3/4 toxicities was low, including neutropenia(21.7 %), anemia(4.3 %), thrombocytopenia (13.0 %). Those toxicities were mainly related with the chemotherapy agents. Meanwhile transient electrocardiogram changes mild ST-T of changes occurred in 3 cases. 2 cases were mild hypertension and were symptomatically controlled. Conclusion There are better efficacies of endostar combined with FOLFOX chemotherapy for advanced/metastatic colorectal cancer, and it is low toxic and tolerable. It is worth of further clinical observation. More experiences need to be accumulated.

OBJECTIVETo investigate the incidence of testicular appendages, observe their morphology, and analyze their histopathological origins.

METHODSWe observed 67 testes in 54 patients (15 children and 39 adults) undergoing scrotal surgery, investigated the incidence of testicular appendages, and identified their histopathological origins. We used the Chi-square test to compare the findings from the children and adult patients, with P < 0.05 as statistically significant.

RESULTSThe detection rates of the appendix testis, appendix epididymis, paradidymis, vas aberrans superior, and vas aberrans inferior were 80.6% (54/67), 23.9% (16/67), 1.5% (1/67), 3.0% (2/67), and 1.5% (1/67), respectively. The incidence of testicular appendages was higher in children than in adults (93.3% vs 80.8%), but with no statistically significant difference (Chi2 = 1.339, P > 0.05), and that of the appendix testis and epididymis with pedicles was significantly higher in the former than in the latter (82.4% vs 54.7%, chi2 = 4.149, P < 0.05). Pathological examination showed that the appendix testis originated from the paramesonephric duct, while the appendix epididymis, paradidymis, vas aberrans superior, and vas aberrans inferior from the mesonephric duct.

CONCLUSIONTesticular appendages consist of five embryonic remnants, including appendix testis, appendix epididymis, paradidymis, vas aberrans superior, and vas aber- rans inferior. The appendix testis originates from the paramesonephric duct, and the other four from the mesonephric duct. The clinical implication of these testicular appendages is their tendency to torsion.

OBJECTIVETo study the feasibility of the modified osteotomy of transcranial orbitotomy in the treatment of intraorbital tumor.

METHODSWe treated 8 patients with intraorbital tumor during six years. By the bicoronary incision, all cases underwent double bone flap osteotomy on the frontal bone: the superior orbital rim bone flap and roof flap instead of single fronto-orbital bone flap in the conventional transcranial orbitotomy. After removal of bone flaps, intracranial and intraorbital operation was performed. Then, two bone flaps were reduced respectively and fixated with titanic micro-plates and nails. At last, the scalp flap was sutured.

RESULTSThe operative field was very well exposed. It was found that the retrobulbar tumor was located at the superolateral, median and superonasal area respectively, which was coincided with the preoperative CT and MRI. The tumor included adenocarcinoma of the lacrimal gland, neurinoma, meningioma, and cavernous hemangioma. Four patients had blood transfusion during the operation. No other postoperative complications happened except 3 cases of diplopia and one case of blindness. After 3 to 6 months follow up, diplopia of the 3 cases gradually disappeared. Of the 8 cases, 6 reached the same visual acuity as the preoperative state. One decreased visual acuity and one lost light perception. There was well-balanced fronto-orbital appearance and eyeball position compared with the healthy side in all cases.

CONCLUSIONSThis surgical method for the treatment of intraorbital tumor is safe with well-exposed operative field. It has advantages not only in simpleness and less trauma, but also in keeping orbital roof and anterior fossa intact and decreasing complications.

OBJECTIVETo investigate the diagnosis and differential diagnosis of extranodal Rosai-Dorfman disease.

METHODSTwo cases of extranodal Rosai-Dorfman disease were studied using hematoxylin-eosin, and immunohistochemical staining, along with a literature review.

RESULTSThe lesions of RDD were characterized by the presence of large histiocytes with emperipolesis, accompanied by infiltration of lymphocytes, plasma cells and other inflammatory cells. The large histiocytes had an abundant cytoplasm, pale to eosinophilic in appearance, positive for S-100 protein staining, with a vesicular nucleus and a small basophilic nucleolus in each cell.

CONCLUSIONSExtranodal Rosai-Dorfman disease is known as an idiopathic proliferative disease of histiocytes with a distinct morphologic feature and is very rare. Differential diagnosis from other types of fibrohistiocytic proliferation lesions is recommended.

BACKGROUNDBreast cancer remains the most important cancer among women worldwide. The disease itself and treatment may have a profound impact on the patients' psychological well being and quality of life. Depression is common in breast cancer patients and affects the therapeutic effects as well as prolongs the duration of hospital stay. However, few studies reported the effectiveness of music therapy on depression and duration of hospital stay of female patients with breast cancer after radical mastectomy.

METHODSOne hundred and twenty subjects were recruited to this clinical trial and randomly allocated to two groups. The experimental group (n = 60) received music therapy on the basis of routine nursing care, whereas the control group (n = 60) only received the routine nursing care. The whole intervention time was from the first day after radical mastectomy to the third time of admission to hospital for chemotherapy. Data of demographic characteristics and depression were collected by using the General Questionnaire and Chinese version of Zung Self-rating Depression Scale (ZSDS) respectively. One pre-test (the day before radical mastectomy) and three post-tests (the day before discharge from hospital, the second and third admission to hospital for chemotherapy) were utilized. Duration of hospital stay was calculated from the first day after radical mastectomy to the day of discharged from hospital.

RESULTSThe mean depression score of all subjects was 37.19 ± 6.30. Thirty-six cases (30%) suffered from depression symptoms, with 26 (72.2%) mild depression cases, 9 (25.0%) moderate depression cases, and 1 (2.8%) severe depression case. After music therapy, depression scores of the experimental group were lower than that of the control group in the three post-tests, with significant differences (F = 39.13, P < 0.001; F = 82.09, P < 0.001). Duration of hospital stay after radical mastectomy of the experimental group ((13.62 ± 2.04) days) was shorter than that of the control group ((15.53 ± 2.75) days) with significant difference (t = -4.34, P < 0.001).

CONCLUSIONSMusic therapy has positive effects on improving depression of female patients with breast cancer, and duration of hospital stay after radical mastectomy can be reduced. It is worthy of applying music therapy as an alternative way of nursing intervention in clinical nursing process of caring female patients with breast cancer.

OBJECTIVETo investigate the effects of ammonium perchlorate (AP) on thyroid functions and mRNA expression levels of thyroglobulin (Tg) and thyroperoxidase (TPO) genes of rats.

METHODSThirty SD male rats were randomly divided into six groups: control group, iodine-deficient group, low dose AP group (130 mg/kg), moderate dose AP group (260 mg/kg), high dose AP group (520 mg/kg) and high iodine-combined group. After the rats were exposed orally for 90 days, serum free-thyroxine (FT(4)), free-triiodothyronine (FT(3)) and thyroid stimulating hormone (TSH) were measured using radioimmunoassays. mRNA expression levels of thyroglobulin (Tg) and thyroperoxidase (TPO) genes were detected by real-time quantitative PCR.

RESULTSSerum FT(4) levels in moderate dose AP group and high dose AP group were [(9.540 ± 1.327) fmol/ml] and [(6.509 ± 1.949) fmol/ml] respectively, which were significantly lower than that [(13.505 ± 1.276) fmol /ml] in control group (P < 0.05 or P < 0.01). Serum TSH level in high dose AP group was [(1.227 ± 0.295) mIU/L], which was significantly higher than that [(0.545 ± 0.282) mIU/L] in control group (P < 0.05). The mRNA expression levels of thyroglobulin (Tg) gene in all groups exposed to AP were significantly lower than that in control group (P < 0.01). The mRNA expression level of thyroperoxidase (TPO) gene in high dose AP group was significantly higher than that in control group (P < 0.05).

CONCLUSIONAP can reduce the serum FT(3) and FT(4) levels of rats, increase the serum TSH level of rats and decrease obviously the mRNA expression levels of Tg and TPO genes. In addition, high iodine can reduce the toxic effects of AP on thyroid gland of rats to some extent.
